Lay and connect the wiring harnesses as follows:
Warning!
The power and control wiring harnesses must be laid separately in order to avoid interference in the control circuit (electromagnetic
compatibility).
Excess cable should be gathered such that current flows in opposite directions and tied in order to avoid any antenna effect.
Lay the wiring harness (power) N1Q_ST11, Y39 from module 1 (liquid dispensing 1 - 6) EZL 235 - Plug connector ST11, to the cold
water intake valve 3/4" (Y39), Fig. 3, Pos. 4a.
For this, pass the cable through the component support opening on the EZL 235 and under the component support to the cold water
intake valve 3/4".
Secure the wiring harness N1Q_ST11, Y39 to the component support with cable ties.
Connect the cold water intake valve 3/4" (Y39) in accordance with the wiring diagram.
Lay the wiring harness (control) N1D_ST13, X3-4 from module 1 (liquid dispensing 1 - 6) EZL 235 - Plug connector ST13 to the
terminal strips 1X3-4, orange and 2X3-4, grey, Fig. 3, Pos. 4b.
Lay the wiring harness (control) N1L_ST11B, N1Q_ST11 from module 1 (liquid dispensing 1 - 6) EZL 235 - Plug connector ST111 to
ELP 235 - Plug connector ST11B, Fig. 3, Pos. 4c.
Lay the wiring harness (power) 20X-41X from module 1 (liquid dispensing 1 - 6) EZL 235 - Plug connector ST10 to ELP 235 - Plug
connector ST14, Fig. 3, Pos. 4d.
Lay the blue connection wire from module 1 (liquid dispensing 1 - 6) EZL 235 - Plug connector ST8, PIN 7 to terminal strip 3X3-4,
blue, Fig. 3, Pos. 6.
